SimpleZ-api

This is a Node.js RestAPI developed for my SimpleZ website. It contains endpoints which allow front-end to send and request data. It got hot-reload feature using nodemon. To host server on your computer simply type npm install then provide your working directory with .env file containing key ACCESS_TOKEN_SECRET and give it a custom value of your choice. Enter nodemon index.js in command line and you are ready to go.

Overview

The most important file on the whole server must be index.js, it contains all endpoints corresponding to given functions that will be called upon request hitting the endpoint. I designed a few controllers located in this folder they contain methods which operate on set of values and manage the data accordingly.

Controllers

I divided the controllers section into three parts Authorization UserControl and Validation.

Authorization file

This file contains method that authorizes every secured endpoint meaning that it guards contents of the page that shouldn't be operatable by users that are not logged in. It checks if JWT token was passed in a request header and verifies it by decoding the token using ACCESS_TOKEN_SECRET In case of successful authorization, user is allowed to access the endpoint. In any other case endpoint is blocked and error is sent to front-end.

UserControl file

It consists of list of methods that allow server to fully operate on user data and its files. It allows to: show signed up users, add user by encrypting its credentials and generating JWT token, log user in it checks credentials and if correct returns JWT token, get user files it returns list of files that given user has created, create file it creates file object and adds it to corresponding user, delete file, load file and patch file which both of these methods are used to edit file in front-end site.

Validation file

This file is based on Joi's validation. It consists of schemas that are used to validate if values of keys of passed objects got valid properties. The validation throws error if any of the properties isn't valid.
